摘要

“长江口二号”古沉船采用一种新型矩形曲线底幕法进行打捞作业,其机械及构造设计存在多方面的挑战.针对免触碰和微扰动的要求,阐述了自主研发的打捞工法配套机械及构造设计方案,包括外部框架系统的组成、行星齿轮三刀盘顶管机的机械构造及具有高止水性能的密合型弧形管节结构设计.实际应用效果表明,所研制的行星齿轮三刀盘顶管机对古沉船的扰动小,所设计的密合型弧形管节间密封性好,有效地保证了“长江口二号”古沉船及其船载文物的原生性和完整性.

Abstract

The salvage of “Yangtze River Estuary II” ancient wreck adopted the world’s first curved pipe basing method. There existed various challenges in the mechanical and structural design. To satisfy the demands of non-contacting and subtle disturbance, this paper elucidates the configuration of the outer frame, the mechanical design of the pipe-jacking machine with a cutterhead of tribble planetary-gear cutters, and the structure design of the closely-assembled curved beam with high water-tightness. The practical application demonstrates that the developed pipe-jacking machine has subtle disturbance to the ancient wreck, and the water-tightness between the closely-assembled planetary-gear cutters is good, both of which effectively guarantee the originality and integrity of “Yangtze River Estuary II” ancient wreck and the cultural relics it carried on.

Key words： curved pipe-jacking; wreck salvage; mechanical design; structural design
